allow custom daemon startup prevention 
don't bother with /sbin/start-stop-daemon and /usr/sbin/policy-rc.d
if they're not a regular files (e.g. symlinks)

Use apt patters to select priority variants 
- requires apt >= 2.3.10
 - we can drop having to run apt-get indextargets and parse Packages
   files ourselves
 - we can drop the layer violation that computed the package set in
   run_download() and passed the package set around in setup() to
   run_install()
 - packages are selected by suite unless the suite is the empty string

c61e81a244 Relax dpkg version regex 
For non-release builds the version will include the number of commits since last release and the commit hash with dashes, e.g. 1.20.8-46-g0881.
For downstream distros it seems it may include their identification strings, e.g. 1.20.9ubuntu2.

Make the regex match everything after the version number to avoid incorrectly erroring on such versions.

Fixes #18

use rm and find instead of remove_tree() 
* remove_tree() requires the CWD to be accessible or fails with
   cannot chdir to $CWD from $DIR_TO_DELETE: Permission denied, aborting.
 * CWD is not always accessible -- example: run mmdebstrap from a
   directory only accessible by the current user (like a tempdir) in
   unshare mode
 * find from findutils *also* requires CWD to be accessible but it's
   easier to temporarily change CWD in a subprocess because using
   there is no utility in perl core that changes CWD temporarily and
   cleans up after itself
 * we need to use find from findutils instead of rm in unshare mode
   because the root directory itself might not be removable by the
   unshared user so we only want to remove its subdirectories

Pass extended attributes (excluding system) to tar2sqfs 
/bin/ping (from iputils-ping) uses the security capabilities to allow
users to use the program:

```
$ getcap /bin/ping
/bin/ping cap_net_raw=ep
```

Debian testing/unstable images (variant important) contain security and
system attributes:

```
$ mmdebstrap --variant=important bullseye root.tar
$ tar --xattrs --xattrs-include='*' -vv -tf root.tar | grep -B 1 '^ '
-rwxr-xr-x* 0/0           77432 2021-02-02 18:49 ./bin/ping
  x: 20 security.capability
--
drwxr-sr-x* 0/102             0 2021-05-07 15:10 ./var/log/journal/
  x: 44 system.posix_acl_access
  x: 44 system.posix_acl_default
```

When generating a squashfs image with mmdebstrap 0.7.5-2, these security
capabilities are lost. Example for building a squashfs image in a
minimal Debian unstable schroot:

```
$ apt install -y mmdebstrap squashfs-tools-ng
$ mmdebstrap --variant=important buster root.squashfs
$ rdsquashfs -x /bin/ping root.squashfs
$
```

tar2sqfs from squashfs-tools-ng 1.0.4-1 supports encoding extended
attributes from the namespace `user`, `trusted`, and `security` (see
`include/sqfs/xattr.h`). GNU tar (version 1.34) supports these three
namespaces plus the namespace `system`.

Passing extended attributes from the `system` namespace to tar2sqfs will
produce an error:

```
ERROR: squashfs does not support xattr prefix of system.posix_acl_default
```

So pass the extended attributes to tar2sqfs, but exclude the `system`
namespace. Then ping will keep its security attributes:

```
$ rdsquashfs -x /bin/ping root.squashfs
security.capability=0x0100000200200000000000000000000000000000
```

gpg: handle ASCII-armored keyrings as well 
gpg command "--list-keys" requires input files to be passed with
option "--keyring" and each file must match type "public keyring v4"
while gpg command "--show-keys" doesn't require extra options and
handles also ASCII-armored public keyrings as well.

skip the emulation check in chrootless mode 
Whenever the selected architecture differs from the native architecture
of the system that runs mmdebstrap, mmdebstrap checks whether it can run
the selected architecture. In the majority of cases, this is good and
helps avoid difficult to diagnose issues. However when running in
chrootless mode, we don't actually want to run any binaries from the
target system. For that reason, the emulation check should be skipped in
chrootless mode.

Preserve extended attributes in tarball 
When specifying a tarball as output format, the extended attributes are
lost. This leads to programs like ping fail to run as normal user.

Therefore preserve the extended attributes when generating the tarball.

--keyring now overwrites the default apt keyring 
- apt can only handle one directory and one file as keyring
 - the signed-by option is used to specify the keyrings for suites that
   are not known by apt

add --man option and reduce output of --help option 
Printing the full man page requires the perl-doc package. To avoid this
dependency, print the less verbose output containing only the synopsis
and the option list for the --help option and print the full output
(requiring perldoc) for the --man option.

also run initial installation of Essential:yes with /proc, /dev and /sys mounted 
In Debian Jessie, init is part of Essential:yes and thus systemd gets
installed which needs working /proc, /dev and /sys

Use parallel xz compression 
One of mmdebstrap benefits over deboostrap is that it is faster.
Creating a xz tarball as output will take a lot of time, since xz
consumes a lot of compute power and tar uses only one core.

Therefore use parallel xz compression since xz supports it using the -T
parameter.

allow multiple --include options and use array instead of hash 
Package order is important when calling apt. Consider this dependency
graph:

    A -> B -> C | D , E -> D | C

"apt install A E" it will install "A B C E"
"apt install E A" it will install "E D A B"
